Groundhoggin It: when one has to take a shit and it is trying to sneak out and you force it back up there and it does the same thing again and again until you eventually let nature take its course in the bathroom.

When you have to take a shit so bad, and so large that it starts occasionally peeking out of your butthole. This usually occurs when your diet is mostly composed of meat. Not to be confused with prairie doggin' it, ground hoggin' it is much larger than prairie doggin'.
